Our take

Northern Lights Auto brings one of cannabis cultivation's most recognized names into autoflower form. With up to 20% THC and a fruit-meets-spice aroma, it suits growers who want a substantial, indica-leaning harvest without the complexity of managing light schedules. The plant is forgiving enough for beginners while producing yields that keep experienced growers interested.

Seed to harvest in 9 weeks flat — no light-schedule changes required at any stage
Indoor yields of 1.6–2 oz/ft² and outdoor yields up to 5 oz per plant from an XL-sized plant standing 35–47 inches tall
Fruity, peppery aroma profile with up to 20% THC in a 70% indica-leaning plant

Growing notes

Northern Lights Auto fits indoor tents, greenhouses, mixed-light setups, and outdoor gardens equally well. Expect plants to reach 35–47 inches — plan vertical space accordingly indoors. The 9-week total cycle from seed to harvest is fixed by its autoflowering genetics, so timing a grow is straightforward. Beginner-friendly but rewards growers who dial in airflow and moderate feeding.
